Patented Nov. 10, 1931 UNITED STATES LOUIS mnnz, or MILWAUKEE, isconsin BURNER earner) Application filed November 16, 1928. Serial No. 319,819.

This invention relates to improvements in burner guards.

During the cooking of liquids over a gas range burner, the, material being cooked is often left unattended for a considerable period of time, during which interval it may boil over and extinguish .the'burner flame.

mal manner, but will render it impossible forv the burner flame to he accidentally extinguished by the overflowing of liquids being cooked on the burner.

A further object of the invention is to provide a burner guard with .which any gas range burner may be readily equipped without any material modification and with a minimum of ex use,

A further object of the invention is to provide a burner guard which is of very simple construction, is inexpensive to manufacture, is strong and durable, is efficient in operation, and is well adapted for the purpose described.

With the above and other objects in view the invention consists of the improved burner guard and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawings in which the same reference characters indicate the same parts in all of the views:

Fig. 1 is a plan view of a gas burner equipped with the improved burner guard;

Fig. 2 is a side View thereof with part broken away and shown in section;

Fig. 3 is a detail sectional view of the burner guard taken on line 3-3 of Fig. 1; 5 and Fig. elis a sectional View taken on line 4-4 of Fig. 3.

Referring now more particularlyto the drawings,,it will appear that the numeral 6 indicates a gas range burner having radially lhe burner guard comprises a plate member 9 ofvsuflicient length-and width and so proportioned as to cover one of the burner fins 7, and said plate member is formed at one end portion with a depending pin or sup porting leg 10.

In'practice, one of PATENT projecting fins formed-with fuel rlfi S T I the burner fins 8 is it formed near itsouter ,end portion with a 7 vertical, slightly taperedaperturell to se curely, but removably receive thelower end port on of the guard leglO, as in Fig. 2. The

length of said guard leg. is suflicientto ele' V vate the guard plate 9 ona,,level; with, or slightly below, the usual burner grating (not shown) on whichlutensils are'positioned over the burner for cooking, 7 1

The guard: plate is .formedaround its inner-end portion and sides with a downwardly and outwardly inclined wall 12,.andthe top surface of the plate, together with the wall, is of a slightly, dished-o or concave. for.-

mation, as shown in Fig. Th l v1O which extends at rightahgles beneath the guard, s formed with agfuel ductlO' which com-' munioates with. the exterior-at 10".

When a vessel containing liquidlis sta tioned onjthe burner grating over the burner,

the burner guard is mounted as shown, and

should any of the liquid boil over, it may extinguish the flames from the unguarded burner fins, but the other fin willbe guarded by the plate portion-9 which will catch liquid and prevent it from flowing onto the fin therebelow. The liquid may run off the outer end of the dished plate portion or over the side walls thereof, but in any instance it cannot drip onto the guarded fin, it being noted that the outward inclination of the walls 12 will direct liquid free of the guarded fin; Even if, through any chance, the flames from the guarded fin are extinguished, the

flame from the point 10", which is fed by the fuel carried through the duct 10, will be absolutely protected as it is directly beneath and adjacent the plate 9 and is guarded by the overhanging sides 12.

Assuming that all of the unguarded burner fins have been extinguished by liquid overflowing thereonto, the flame will still remain two burning from the guarded fin and this flame will again ignite the gas from the fins which had their flames extinguished. Even if the flames from the guarded fin are extinguished, the flame from the point 10 will remain burning toignite the entire burner. Hence there is no danger of escaping gas for any considerable period from aburner equipped with the improved burner guard. 7

Although the device is shown in attachment with a burner of star shaped formation, having fins, it is to be understood that it may be used to protect a portion of a burner of circular or any" other shape.

From the foregoing description it will be seen that the improved burner guard is of simple and novel construction and is well adapted for the purposes described.

7 *What I claim as my invention is:

1. A guard for a burner having fuel orifices, comprising a plate having depending side portions, open at one end, and a dished mid-portion and having a depending leg adapted to' be positioned within a fuel orifice of the burner, said leg being formed With a duct therein adapted to direct fuel from the burner to'a point of discharge beneath the plate, theflame resulting from the ignition of'said fuel andissuing from the point of discharge being protected by the plate and by the depending side portions thereof from V extinguishment by overflowing material, and

7 being adapted to reignite the burner Where the latter is extinguished because of overflow of material thereunto.

'2. The combination with a gas burner having fuel orifices and a, fuel line extending to the burner -to"'supply fuel thereto, of a guard memberfor shielding only a portion of said burner to protect flames issuing from said portion from being extinguished by overflowing material, comprising a slightly dished plate partially surrounded by down Wardly, outwardly extending sides, and a leg supporting said plate and removably insertedin a fuel orifice of the burner, said leg being formed with a duct therein communicating with the fuel "line to the burner and having a protected discharge opening immediately beneath said plate.

- In testimony whereof, I afiix my signature.
